The teeth from the Cretaceous bed of the Bushman's Eiver which have 
hitherto been placed under Anthodon are held to be Dinosaurian, and for 
them the new name Palacoscincus africanus is proposed. 
The " Odyssey of our Bushman Boy," by Miss Currle. It is the 
narrative of the life of an old boy, Gert," of the type usually called 
Bushman at the Cape, partly told by himself, partly by Miss Currl6, 
whose family the man had been serving for some time. From the events 
narrated, the man is extremely old, and certain traits of his character and 
domestic habits are well worth recording now that the race is almost 
extinct. 
" Notes on a Zoological and Botanical Collection from the Group of 
Islands of Tristan d'Acunha, made by Mr. J. C. Keytel, 1908-09," by 
L. Peringuey and E. J. Phillips. 
The botanical specimens came from Tristan only, while a few birds 
were obtained from Nightingale Island; the remainder, however, was 
collected at Tristan itself. Mr. Keytel collected seven of the twenty 
species endemic to the island, as well as sixteen plants that have been 
introduced within the last thirty years, as no mention is made of them by 
Moseley, of the Challenger expedition ; among the birds was found a 
cuckoo, a native of South America, Coccyzus melanocoryphus. Among the 
insects all but two are introductions mainly from the Cape, but also from 
extreme South America. The Cape Crawfish, Jasus lalandei, occurs also 
at Tristan, as well as several fishes found on the Cape Colony coast. 
"Absorption of Light by the Atmosphere," by A. W. Egberts. The 
investigation was undertaken for the purpose of obtaining a value of the 
coefficient of absorption for South Africa. Taking the means of all the 
results, Dr. Eoberts obtains as the value of the coefficient of atmospheric 
absorption 0™ 20, which interpreted into other terms means that 17 per 
cent, of all rays that strike the atmosphere perpendicularly are absorbed 
by the atmosphere. 
''The Age of Stone (Palaeolithic) in the Drakenstein Valley and the 
Manner in which the Implements were Made," by L. Peringuey. A 
large collection of implements of a huge size were exhibited. It was 
found possible from the material found in that valley to reconstruct the 
artificial working of those implements from the fractured, water-worn 
quartzite boulder to implements of a finish equal to the best Acheulean. 
The division of Chellean, Acheulean, Mousterian cannot be adopted in 
South Africa, as the three typical forms were found together and in all 
stages of finish. The extreme antiquity of the implements shown was 
demonstrated by the well-nigh disintegrating sandstone of which they are 
made, as well as by the abraded edges of many of these palseoliths. In 
fact, some that had been long exposed seem to be preserved by the patina 
they acquired through the exposure.
